PROCESS FOR PREPARING CAPROLACTAM

PROCESS FOR PREPARING CAPROLACTAM

Caprolactam is prepared by cleaving oligomers or polymers containing essentially the repeating unit -[-N(H)-(CH2)5-C(O)-]- in the presence of a catalyst at elevated temperatures by a process in which the cleavage is carried out in the liquid phase in the presence of a heterogeneous catalyst and of a...

Zusammenfassung:Caprolactam is prepared by cleaving oligomers or polymers containing essentially the repeating unit -[-N(H)-(CH2)5-C(O)-]- in the presence of a catalyst at elevated temperatures by a process in which the cleavage is carried out in the liquid phase in the presence of a heterogeneous catalyst and of an organic solvent.
